With TORELIEF* CTP, you can achieve simple plate-making procedure and finer image reproduction.
You can eliminate primitive plate-making faults with use of negative film, for example dust entrapment or light scattering.
Sharper dot, deeper reverse image, and finer halftone image can be reproduced with CTP, because of direct exposure to plates.
We offer you Y-type base CTP and W-type base CTP.
The table below shows comparison of each plate types' characteristics.
| Y-type base CTP | W-type base CTP | |
|---|---|---|
| Image Reproducibility | Excellent | Good |
| Durability | Good | Excellent |
